(SET ITAL) Dear Carrie: Several of my friends and I (all in our early 60s) are understandably thinking about Social Security. Everyone seems to have different ideas -- and different information -- about when to apply for benefits, how to apply, and how much we can expect to get. Can you give us a straightforward answer on what we should know? -- A Reader (END ITAL)

Dear Reader: Since Social Security plays such a big part in people's lives, you'd think we'd have a better idea about how it all works. But on the contrary, a lot of folks don't fully understand their benefits or, more importantly, how to maximize them.

It's essential to take some time to consider your options before you apply, or you may miss out on thousands of dollars over your lifetime. There's a lot of helpful and detailed information at socialsecurity.gov, but for starters, here are five important things you and your friends should focus on:

1. UNDERSTAND HOW TIMING AFFECTS BENEFITS

With all the talk about the future viability of Social Security, many people think they should apply for benefits as soon as possible. But there's more to it.

In a nutshell, if you file at the earliest possible age, 62, your benefit is permanently reduced. If you wait until your full retirement age (FRA), which would be 66 for you and your friends, you collect 33 percent more. Wait until 70, and your benefit goes up by a total of 76 percent!

There's a point where total benefits balance out (a larger check for a shorter time), but, generally speaking, if you're healthy and longevity runs in your family, you'll increase your total lifetime benefits by postponing your start date.

In terms of timing, you also have to consider your work plans. If you take benefits before your FRA, and your income exceeds certain limits, part of your benefit is temporarily withheld. In 2014, $1 dollar in benefits is withheld for every $2 you earn above $15,480. The year you reach your FRA, $1 is deducted for every $3 you earn above $41,400. However, you do get this money back as an increased monthly benefit once you reach your FRA.

Taxes are another thing. Regardless of when you take benefits, 50 to 85 percent of your Social Security income may be taxable if your modified adjusted gross income reaches certain levels. For 2014, that's between $25,000 and $34,000 for individuals, and between $32,000 and $44,000 for married couples filing jointly. Your benefit might also bump you into a higher tax bracket. Best to discuss this with your tax adviser.

3. STRATEGIZE WITH YOUR SPOUSE

Working as a team, married couples have some choices that can significantly boost their combined benefit. That's because of the spousal benefit allowing one spouse to take up to 50 percent of the other's benefit (as long as that spouse has already filed), while letting his or her own continue to grow.

There are a number of ways to do this. For instance, in a strategy sometimes called the "62/70 split," the lower-earning spouse takes Social Security as early as age 62, while the higher earner delays until 70. In the meantime, the higher earner can take the spousal benefit as a bonus.

Another option is for the higher-earning spouse to apply for benefits at FRA, and then suspend them. The lower-earning spouse could then collect a spousal benefit based on the higher earner's record, while the higher earner's benefit continues to grow. This can get complicated, so, again, best to consult with a financial professional. But it's definitely worth exploring!

4. FIND OUT HOW MUCH YOU'LL COLLECT

Everyone age 60 or older who hasn't yet applied for benefits is mailed a yearly Social Security statement. This provides an estimate of retirement and disability benefits, as well as survivor benefits. Or you can create a personal account at socialsecurity.gov to access your statement. The site also has a number of calculators, which you can use to explore how different start dates or continuing to earn would affect your benefit.

For 2014, the maximum monthly benefit for a worker at FRA is $2,642. The estimated average monthly benefit is $1,294. And FYI, you can apply for benefits online when you're ready -- up to four months before your start date.

5. BE AWARE OF SURVIVOR BENEFITS, BENEFITS FOR EX-SPOUSES AND DISABILITY BENEFITS

While exploring timing and benefit amounts, it's also important to be aware that:

--At FRA, a widow or widower can collect up to 100 percent of a spouse's benefit (or reduced benefits at age 60). If you collect early and receive reduced benefits, that reduction also applies to your surviving spouse.

--Under certain circumstances, you can collect benefits based on an ex-spouse's record without affecting what your ex or your ex's current spouse can collect.

--If you're disabled and under full retirement age, you and your family members may qualify for disability benefits.

These basics are the same for everyone, but the individual decisions you and your friends make may well be very different. You'll each have to thoughtfully consider your choices based on your circumstances. In the meantime, this information should give you a lot more to talk about!
